Phone replaced under warranty through LG 1 yr warranty

Just an update.... I sent my phone to LG for warranty repair to fix the dead spot issues and they sent me a factory reconditioned phone back. Didn't even try to fix my original phone. Took 1 week to get phone back from time I put mine in the mail. Everything working now for the last 3-4 weeks. Pretty good service I'd say for LG.
[G2 Q&A, Help & Troubleshooting] HerrJuancho:
I'm having this issue on the 801 model (T-Mobile LG G2). I have resetted it about 3 times now, and it starts to work better, but slowly starts to develop the problem again.

So the answer is to flash th VZW's software over the T-Mobile's) (is it even possible?) :confused:
[G2 Q&A, Help & Troubleshooting] Sfkn2:
You're able to fix this with a hard reset?!
[G2 Q&A, Help & Troubleshooting] HeXaLox:
How long did this take? as in the whole process... including the 1 week
[G2 Q&A, Help & Troubleshooting] TheJuicer:
Really took about one week total. 2 days in mail to them. They had it about 4 days and then two days back to me. So I guess 8 days would be more accurate. The ability to check service repair on the website is nice. Phone still working great.

i had similar problem with my g2 d802 international - when in quick memo i couldn't draw a line thru the middle of the screen, couse as soon as my finger hits that zone, drawing stops - i found that this was a software issue, and all i did was a clean kdz (open europe V20D) installation and problem disappear

false positive - it was good for about 24 hours now its crappy all over again ... i think its autocalibration issue or something with w screen itself ... just called lg support and im giving mine back for warranty ... hope they will fix this

Yes! Drives me nuts. I've tried different Roms, different keyboards. It's only when the keyboard is up. The rest of the time the screen is fine.
[G2 Q&A, Help & Troubleshooting] beachmiles:
I too only seem to have trouble when the keyboard is open. The 2 leftmost navigation buttons don't work. But once the keyboard is gone they work again. It has to be a software issue. I have tried many ROMs, some have the issue when the keyboard is not open as well. This just started happening a week ago for me. Sucks!!

can u guys check, touch response reduces, if it is placed on bed or a glass top table.

ie, place it on u'r bed,open quick memo and check for responses.don't touch it with u'r other hand.

another method is place it on u'r bed or glass table,go to settings-> mobile data usage and then open quick memo application an draw somthing.try this with mobile data turned off and on.please check and post results

Installed Mahdi's ROM and now my keyboard does not kill my soft keys! It looks like kit Kat's immersive mode may be the culprit. Mahdi's ROM defaults to disable immersive mode which is AWESOME! Very weird that I was running cloudys gpro ROM with no issues for months and suddenly got the issue.

I had previously tried many other ROMs to try and fix it and mahdi was the only fix.

Just started to experience "- The inability to draw a straight line in a drawing app- your straight line gets interpreted on-screen as a jagged, EKG-like readout"

This (i think, i've lost track by now) will now be my 7th LG G2 :( Just like all of the other screens, it starts off with one of the shown flaws, jagged lines, twitching of the screen, random touches etc, and then turns into a dead spot a few weeks later stretching horizontally across the screen.

Thanks AT&T for being so understanding, they seem to be well aware that these touchscreens are awful and gave me yet another warranty exchange, but gave me no indication of whether or not LG was aware of their hardware/software faults...

If I wasn't moving in a year I would bite the contract bullet and switch brands, but looks like I'll have to hope this one lasts!

phantom touches

Hii Guys.

I am also experiencing that issue but mainly random phantom touches. Sometimes even in middle of the night.

My LG G2 (D802, 4.4.2 ) draws straight lines. but this touch glitch is very annoying.

Can anyone tell me how likely this is a software issue?. Cause if it is I can unlock, root it and install new ROM . I planned this eventually, but if it's hardware issue than I need to think about sending it back to manufacturer.
[G2 Q&A, Help & Troubleshooting] Rayan:
Quite honestly in my humble opinion and experience with my LG G2, these are not software problems (phantom touches and dead touchscreens spots).

If they where software issues, a simple Kernel, ROM, Recovery change would fix them, which does not! In fact, I'm starting to believe it's not even a touchscreen issue at all, but a touchscreen controller issue or a voltage regulator issue instead since many people have replaced the whole screen panel only to discover the problem coming back after a few weeks or so.

Gonna try to have it fixed by LG, however I don't have much hopes on it since many people have done that already several times only to find the problem coming back again!

Cheers and good luck with yours!
[G2 Q&A, Help & Troubleshooting] Sfkn2:
This happens only when the phone is warm; ie: watched a youtube video for 30 mins then placing it flat on the bedside table. The touch screen does not work at all until I lift the phone again.

Mobile data usage does not matter in this situation.
[G2 Q&A, Help & Troubleshooting] Rayan:
In my case it does not work no matter if I hold the phone on the left hand, right hand, over a table, over the bed, over glass, with or without silicone case, with or without quick window case, you name it, I've tried everything!

However something strange happened yesterday morning. When I picked it up to go to work, I noticed that the screen was working flawlessly, I even tried to reproduce the drawing over the screen to detect dead spots and all was good and dandy! But after a few hours of very minimal use, the problem came back again!

My dead spot has been dead for more than a month and even getting worse and worse to the point of now having random ghost touches, but then out of the blue one day it decides to revive for a few hours without me doing anything to fix it? It simply does not make any sense whatsoever except to think:

1. Sunspots?

2. Electromagnetic shifting of the earth?

3. Ghosts?

4. All of the above?

:silly::D:eek::rolleyes:

Cheers!

Hello again

I finally received my new screen (after 2 months but that's a different story) and replaced it today. So far I can tell that the issues have been resolved, so unfortunately it really seems to be a hardware problem (see my older posts).

So if you have similar problems like I had (see https://www.youtube.com/watch?v=zDNoQ4WHxjQ ) it is probably a hardware issue. Although it could be coincidence that the problems haven't appeared until now. Yet I highly doubt that because in my case it used there almost all the time...

If it reappeared I would post an update.
[G2 Q&A, Help & Troubleshooting] Rayan:
I'm really looking forward on your progress, since I've read several people that have replaced their screens only to see the problem come back to haunt them.

I haven't taken the plunge to fix it myself since I think it's a waste of money and also because I just got a smartwatch and I've been somewhat distracted by the novelty of the new gadget... :rolleyes:

Let us know how it goes!

[G2 Q&A, Help & Troubleshooting] Detalos:
I'm not sure if this has been posted yet but I ran across the same issue you all seem to be experiencing right after replacing the USB port in my D800. after a few hours of frustration and fiddling I went and swapped the original part back in and voila no dead zone. There seems to be a faulty set of pins on the display port connector associated with the factory USB/headphone part. For reference I was having this issue only after replacing the original part the dead zone was on the top portion of my screen slightly thicker than the Google now bar on the GELauncher that ran from one side of the screen to the other and would allow input/ghost swipes intermittently. I did my testing with the developer tools and added trace and touch input coordinates. Hope this helps.
[G2 Q&A, Help & Troubleshooting] Rayan:
Interesting, however some things are not clear to me:

1. What was the initial problem with the USB port?

2. The touchscreen actually have two halves and two connectors, one on top and one on the bottom of the device.

What could be the relation between the USB port with the top touchscreen connector?

If your dead zone where on the bottom then I would understand due to close proximity or something. But the one on top?

The other day I went in and reseated the top connector but skipped the bottom one since my dead zone is located on the top part, but according to your experience it seems like the bottom connector has something to do with the top of the touchscreen also.

I'll try to reseat the bottom connector and see if that helps.

Thanks for sharing your experience.

Will post once I do that.

Cheers
[G2 Q&A, Help & Troubleshooting] Detalos:
According to the video i watched (from fixez.com) for instruction on how to replace the headphone/USB port there is a connector(longer rectangle) located next to the camera that is also a portion of the part i was replacing.

He refers to it as a "display connector". The original problem was actually due to a faulty headphone jack, the replacement part i needed also contains the USB port and a few other items (microphone,loudspeaker etc.) The video i watched to do the repair can be found on youtube. I have swapped the two pieces back and fourth now 3 times to test and i have gotten the same results. The factory OEM replacement causes a dead zone across the top of my screen while the original part doesn't(though it still has a broken headphone port.) Upon a close inspection of the Female side of the connection( the portion on the replacement part) there seems to be a few malformed pins(misshapen or bent pins). This is the only significant visible difference i can identify between the 2 parts. So through process of elimination I have come to the conclusion that this is the primary source of the issue(assuming this is in fact a display port connector).

*Edit 1* I'm a novice at cell phone repairs so forgive me for not using official part names. The part in reference here is marked as "Charger Port Headphone Jack Mic Flex Cable For LG G2 D800 D801 D803" on the order invoice. The connector in question is the female connection located on the left upper arm of the part directly beside the power and volume connection
[G2 Q&A, Help & Troubleshooting] Rayan:
Thank you for your explanation Detalos, this makes some sense why in my case my touchscreen dead spot sometimes comes back from the dead and then all of a sudden it goes out again!

I haven't noticed but it could be that it comes back and goes out when I plug or unplug either the USB charger or headphones. I'll pay more attention next time this happens.

Cheers!

I am beginning to feel it is triggered by a rom or kernel. i discovered that each time i switch to xdabbeb, my dead zone gets worst and the zone expands. meanwhile on cloudy G3 everything stays as it is.

I have a d802 version. My phone is only affected by ghost touches, no dead zones... The touches are able to turn off the screen triggering a double touch when the screen is on. I tried to get rid of the problem flashing cloudyg3 but it is still there. Is there something software related I can try, or my only option is LG assistance/replacing the screen?

[G2 Q&A, Help & Troubleshooting] AlionVentus:
I have an D803 Rogers Variant LG G2 flashed CloudyG3 2.0 on it.

The touchscreen gets progressively worse when I leave it on. However I feel my situation might be more fixable than others cause I see that the touchscreen works normally when plugged in and charging. I thought it was voltage issue so I tried to overvolt it, however no luck. Could this be just a simple battery replacement or screen replacement? I don't have warranty on this phone so I don't have the chance of getting a replacement. Anyone who can help should PM me thanks!
[G2 Q&A, Help & Troubleshooting] Rayan:
Interesting that for you it works great while plugged in.

But at least in my case, the dead zone appears to be the most common of all, the upper part at the exact height of the power button, and interestingly enough, the area where the dead zone is located is also the part of the device that gets the hottest, and in my case my G2 failed during a very hot and humid day.

It got so hot that I could barely use it against my ear. Really that bad.

I also notice that the ghost touches occur the most while the device gets hotter.

One more thing worth mentioning, I had enabled the High Temperature Property Off to "avoid stuttering" on some apps.

So in my opinion it's just a matter of bad thermal design or something like that.

Sometimes when the device becomes unusable due to ghost touches, I throw it in a freezer bag and into the freezer for a few minutes a day the ghosts go away for a while.

Hi everyone!

New here - first post.

I, of course, am experiencing the same problems as everyone else in regards to the lg g2.

The thing that I've noticed, and I'd love it if you could all check this out to see if the same happens on your own phones, is that I can actually stop ALL ghost touches and the screen going crazy completely at will.

I do this by applying pressure to the screen just to the right of the earpiece speaker. If I pinch this spot between forefinger and thumb and apply a reasonable amount of pressure, the screen works absolution perfectly. I don't know if this is the same with anyone else's phone but I'd love to know if this is the case.
[G2 Q&A, Help & Troubleshooting] Rayan:
Welcome Avon777, well yesterday out of desperation and frustration with the ghost touches, I did the iPhone-Bend thing with my G2 and suddenly the ghost touches stopped altogether for hours and hours. Maybe I did pressed the area you just mentioned. I will try to apply pressure just on the area to the right of the earpiece and see if that helps.

I also noticed that the ghost touches appear more often when my battery is on the red and almost non existent when over 60, 70% or near full.

Cheers!
[G2 Q&A, Help & Troubleshooting] Avon777:
Hi Rayan (and everyone else),

If your screen started working after a bit of a bend then you may have the same problem as myself, and if that's true then I have some good news for you.

After a little thought and a little tinkering, I now believe that my touch screen is fixed. I realise that you've probably heard this all before but I've been living with the issue for quite a while now and been down the route of new screen, new rom, changed kernel, updated touch firmware, complete battery drain, etc, etc and this is the first time that the screen has been consistently behaving itself and actually feels like it will stay that way. I haven't had one ghost touch or swipe. Also not one screen freeze.

What I have done is remove the back cover, then remove the screws and top back plastic cover that protects the mainboard. I then turned on my phone and pressed the board in the position that I mentioned in my previous post to find the right spot that cures my screen problem. After that I simply folded a little paper, taped it to this spot on the mainboard and replaced the cover, screws and back cover. This provides a constant pressure to that spot.

I did this last night just after I posted my message and have been testing it thoroughly ever since with constant use, benchmarking apps, games, videos, youtube, basically everything I can throw at it. It has been faultless. I also charged that battery fully and drained it almost to nothing then repeated. Absolutely no problems so far.....fingers crossed! :)

I can't say that this will last forever or indeed work for everyone, but if you've tried everything else then its got to be worth a try. It's also very easy to do. Please let me know what you think.:)
[G2 Q&A, Help & Troubleshooting] Rayan:
That's great news Avon777!

However the ghost touches are the least of my G2 problems since the dead zone on my touchscreen is ever present no matter what I do.

There have been just a couple of times where out of the blue, the dead zone regained consciousness only to go dead again after a few hours and I have not been able to reproduce the temporary fix.

I'm still under the warranty window but I've been soooo lazy to get it back to stock and un-root, but I will do that this weekend. Once I get it back, off it goes to Craigslist.

Cheers and thanks for the great news about the ghost touches! :good:
[G2 Q&A, Help & Troubleshooting] Avon777:
I too had a deadzone along the top third of the screen (seems to be the most common place), but this is now gone too. It's really only dead because the screen phantom clicks on this strip a lot of times making it completely unresponsive (you can see this in action if you turn on 'Show Touches' under Settings - Developer options).

Open up your phone and give the folded paper trick a go - it might solve all your problems and save what otherwise is a really good phone. :)
[G2 Q&A, Help & Troubleshooting] Rayan:
Are you serious? Is your deadzone gone too?

I guess I'll give it a shot RIGHT NOW!!!

I'll post my results...

Thanks again! :highfive:
[G2 Q&A, Help & Troubleshooting] Avon777:
Good luck mate. Hope it works for you too.

If it's any help I've attached a picture of the position that I placed the folded paper. I put it right on top of the touch screen flex cable just on the spot that's marked out on this lg g2 mainboard picture.
[G2 Q&A, Help & Troubleshooting] Rayan:
Unfortunately it did no difference at all, which makes me wonder how broad this problem is actually.

Some people have dead zones after a fall, some other out of the blue. Some others have dead zones AND ghost touches, some have fixed it through software others with a touchscreen replacement, some have fixed it permanently, some others the problem comes back.

This makes no sense at all...

I guess I have no option but to send it back.

Cheers and thanks anyway!
[G2 Q&A, Help & Troubleshooting] AlionVentus:
Tried to apply pressure to the same spot, did not work. I really think my ghost touch issue is really the battery and voltage. I can't figure out why its perfectly working when the phone is charging and terrible when it is not. Most likely what I would have to do is replace the battery, the battery life is really weird on my phone. It gave an estimated time for discharge to 0% at 64 hours! And thats with the screen always on and at 100% brightness.
[G2 Q&A, Help & Troubleshooting] em_2516:
Apparently found a fix for the ghost touch screen issue.....try it out.

Hey guys!

I just wanted to share this info I found with you:

Disable & erase Accuweather from the settings & home screen. A guy with this issues called LG for assistance and the rep told him to disable the Accuweather app. In some cases, erasing it from the home screen fixes the issues too.
[G2 Q&A, Help & Troubleshooting] Rayan:
In my case that was the first thing I tried since the ghost touches were enabling the app but it didn't helped to avoid the ghost touches unfortunately.

My G2 was sent under warranty for repairs or exchange.

This has not been resolved. LG has not addressed this manufacturing defect publicly.

The only "solution" would be to return it for warranty repairs or exchange, however odds are pretty high that the problem will come back.

g2 screen issues

Hello, I have a g2 that has the same screen issues. I think I may have discovered where the problem lies. I have disabled all of the lg g2 specific features that are not native to the android os and haven't had an issue with the screen since, or until I turn one of them back on. That is knock on, qslide, and other special functions that are exclusive to our g2. I think what is happening is that the android core, not being familiar with, or having conflicts with these functions is causing the erratic behavior. Its like the system wigs out when it encounters functions it isn't familiar with. If some of you out there could try this and report back it may shed some clarity on this issue.

---------- Post added at 02:35 PM ---------- Previous post was at 02:27 PM ----------

I must add though, the dead spot (a half inch wide dead zone about an inch from the top of the screen) is still there. This though I think is a hardware failure as a result of the conflict and I don't know what could be done about this.
[G2 Q&A, Help & Troubleshooting] Rayan:
At least for me that was not the case, since I had the touchscreen problem even on non stock ROM, I tried several Cyanogenmod versions and also MIUI and all had the same touchscreen issue.

Actually I don't believe it has anything to do with LG ROMs or any other ROM whatsoever since the touchscreen issues are present even while in the TWRP recovery.

But thanks for sharing your experience.

Cheers
[G2 Q&A, Help & Troubleshooting] slickwidnick:
could it be maybe that the lg stock firmware with the extras that i mentioned causes the touch screen hardware to be broken and then the effect is maybe carried over to any other roms simply because the glitch permanently damages the touch screen? like when the phone is sleeping the waiting for the knock on double tap could be something that the core android firmware isnt expecting or something, i dont know, just throwing stuff out there... im curious to know if anyone else out there could try turning off knock on, qslide, and slide aside for a day or so and post the result...
[G2 Q&A, Help & Troubleshooting] Rayan:
For me that is highly unlikely since I never used those features to begin with. I disabled those since day one and all my problems with the touch s screen started while I was on Mahdi ROM, not LG.

However there seem to be different causes of touchscreen failures, some fail after a fall, some after overheating, some after just a few drops of water over the display, some after applying a screen protector, some out of the blue.
